摘要

目的初步探讨早孕期胎儿心率变化规律

建立参考值范围。方法收集2016年1月至2018年1月于我院产前检查的早孕期胎儿的胎心率及孕妇的相关临床资料。应用超声测量胎儿胚芽或头臀长（CRL）

观测胎心搏动

M型超声或脉冲多普勒测量胎心率。结果孕龄40～41 d或CRL 2～3 mm时胎心率为（117.31±11.64）次/min

胎心率随着孕龄或CRL逐渐增加而上升

并在孕龄63～69 d或CRL 23～30 mm时胎心率达到峰值（172.69±9.27）次/min

随后胎心率随着孕龄或CRL的增长缓慢下降

趋于稳定。基于各时期胎心率变化规律建立回归方程:胎心率=-223.751+11.746孕龄-0.086孕龄

（R

=0.772

R=0.877

0.001）;胎心率=101.83+5.108CRL-0.084CRL

（R

=0.765

R=0.875

0.001）。结论以孕龄及CRL为基准

初步建立了早孕期第5、50、95百分位胎心率参考值范围

为临床预测流产风险提供参考依据。

Abstract

Objective To establish preliminarily the reference range of embryonic/fetal heart rate（EHR）during early pregnancy

and to explore its rules.MethodsThe EHR and clinical data of pregnant women and embryos from January2016 to January 2018 in our hospital were collected.Embryonic/crown-rump length（CRL）and the heartbeat was detected by ultrasound.EHR was measured by M mode ultrasound or pulse Doppler.ResultsWhen CRL was 2～3 mm or gestational age（GA）was 40～41 d

the EHR was（117.31±11.64）beat/min.EHR increased with the GA/CRL gradually increasing

and at the63～69 d of the GA or CRL was 23～30 mm

the EHR reached the peak of（172.69±9.27）beat/min.After that

the EHR gradually decreased and tend to be stable with the increase of GA or CRL.The regression equation was established based on the changes of EHR in each period:EHR=-223.751 + 11.746 GA-0.086 GA

（R

=0.772

R=0.877

0.001）

EHR=101.83 + 5.108 CRL-0.084 CRL

（R

=0.765

R=0.875

0.001）.ConclusionBased on the GA and CRL

the reference range of EHR for the 5 th

50 th and 95 th percentiles in the early pregnancy period is initially established

which can provide a reference for abortion risk prediction in clinic.
